Abstract: A photoelectron microscope wherein a normal conductive coil is used to produce a divergent magnetic field to form an enlarged photoelectron image of a specimen to be examined. The coil is only momentarily energized by pulse current, and in synchronism with the energization of the coil and while the change of the resultant magnetic field with time is small, the radiation source is actuated to produce a radiation pulse so that the photoelectrons produced upon irradiation of a specimen with the pulse flies through the magnetic field so as to be received by an image forming device. The image forming device is operated in synchronism with and a predetermined variable period of time after the actuation of the radiation source thereby to obtain photoelectron images of the specimen of different energy levels. By skimming only those photoelectrons of low energy which are emitted close to the axis of the magnetic field, it is possible to obtain images of high resolution.

Abstract: A store-in cache memory system for a multiprocessor computer system (10, 12) has a status entry in the cache directory which is R0 (read-only) when a line of data is read-only, and thus accessible by all processors on the system, or EX (exclusive) when the line accessible for reading or writing but by only by one processor. In addition, each directory has an entry, CH, which is set when data in the line is changed. The cache memory system includes two additional statuses, TEX, or temporary exclusive, and TRO, or temporary read-only. When a data fetch instruction results in a cache-miss, and a line containing the requested data is found in a remote cache with an EX status and with its CH bit set, the line is copied to the requesting cache and assigned a status of TEX. The line of data in the remote cache receives a status of TRO. If a store operation for the data occurs within a short time frame, the status in the requesting cache changes to EX and the line in the remote cache is invalidated. Otherwise, the data in the line is castout to main storage and the status of the line becomes RO in both the requesting and remote caches. The addition of these statuses allows the cache system to assign an exclusive status on an anticipatory basis without incurring penalties when this assignment is not appropriate.

Abstract: A programmable interconnection circuit includes first and second ferroelectric capacitors which differentially store the programming state of the circuit. A principal application of the circuit is in the programming of cells within a gate array integrated circuit. The programmable circuit is non-volatile due to the storage of polarization states within the ferroelectric capacitors. Differential voltage states are applied to programming nodes which set the state of a cross-coupled amplifier that, in turn, drives p-channel and n-channel transistors which are connected between first and second nodes of the integrated circuit. A drive line signal applied to terminals of the ferroelectric capacitors goes between high and low voltage states to set differential polarization states into the capacitors. Following restoration of power to the integrated circuit, which includes the programmable circuit, a pulse is applied through the drive line to the ferroelectric capacitors to create differing voltages at the program nodes. These different voltages are differentially amplified to produce the required voltage states to reestablish the programmed interconnection for the circuit.

Abstract: An electronic control system for determining the resonant frequency of and driving ultrasonic transducers in a phacoemulsification probe used for ophthalmic surgery. The control system includes a voltage control led oscillator, power amplifier, power monitor, and automatic gain control circuit operating under the direction of command signals received from a microprocessor-based control console. The control system operates in a constant apparent power, direct drive mode with closed loop feedback maintaining the electrical power provided to the primary of a RLC transformer at the constant level requested by the command signals from the console. The frequency of the drive signal is held at the dominant resonant frequency of the ultrasonic transducer which is being driven by the control system. This resonant frequency is determined via a calibration procedure performed when the probe is first attached to the control system. During this procedure a constant voltage drive signal is swept through a range of frequencies and the electrical power consumed by the transducer is measured and stored at selected intervals such as 100 Hertz increments. The resonant frequency is also determined in part by looking for the frequency at which maximum power is consumed by the probe. The stored data is   also subjected to other tests to cheok that the peak is indeed a resonant frequency and that the probe has selected output power characteristics about this resonant frequency thus helping to ensure that the probe is capable of operating satisfactorily when driven by the control system.

Abstract: A transparent light-emitting diode has front (14) and back (12) parallel faces and a plurality of side faces (11) perpendicular to the back face. Diagonal faces (13) interconnect each side face (11) with the front face (14) to form a truncated polygonal pyramid surmounting a polygonal base of the light-emitting diode. Because some of the light impinges on the diagonal faces (13) at an angle less than the critical angle for total internal reflection (ϑc), from 1.5 to 2 times as much light is extracted from the LED as a conventional rectangular LED without the diagonal faces. The diagonal faces (13) on the LEDs are readily made by sawing V-­shaped grooves in the front face of a wafer (21) on which the LEDs are fabricated.

Abstract: A wheel rim displacement measuring apparatus which measures radial and axial displacements of a rim wall on the basis of a nut seat pitch circle. A wheel (1) to be measured is mounted on a lower head on the basis of a hub hole center (H) and rotated about an axis of the lower head (10). An upper spindle (21) which is horizontally displaceable relative to the lower head (10) is adjusted in position so as to align with a nut seat pitch circle center (N) of the wheel and is rotated about the axis of the lower head (10). A Fourier analysis is carried on a wave of the displacements of the upper spindle (21) so that an eccentricity amount of the nut seat pitch circle center (N) from the hub hole center (H) of the wheel can be calculated from the first harmonic. In a computer (60), a wave of the displacements of the rim wall measured on the basis of the hub hole center (H) is amended in calculation to a wave of the displacements of the rim wall from a true circle having a center at the nut seat pitch circle center (N) using the first harmonic wave.

Abstract: An optical sensing array (52) is adapted to filter incident light so as to generate two output electrical signals from two different portions of the array. The sensing array, which can be a linear CCD array, is assembled with a glass filter (53) overlying the array, the filter being coated with a material (54) which transmits light over a selected wavelength range. One portion of the glass filter is uncoated (55). Thus a light source incident on the array will activate two separate parts of the array; one underlying the uncoated part and the other underlying the coated portion. This results in two different responses over different portions of the spectrum and results in generation of two electrical signals of different levels, representing different detected wavelengths of light. These electrical signals are useful to represent different functions; for example, various characteristics such as the background density and size of a document being copied on a xerographic copier.

Abstract: An orthogonal light plane generator is associated with a primary light plane generator (100) to convert a portion of a first light plane (108) projected by the primary light plane generator (100) into a second light plane (110) substantially orthogonal to the first light plane. The orthogonal light plane generator comprises a diverter (102) which defines three or more reflecting surfaces for receiving a portion of the first light plane (108) and redirecting that portion as the second light plane (110). The three or more reflective surfaces are oriented relative to one another such that tilting of the orthogonal light plane generator is compensated to maintain the orthogonality between the two light planes. Tilting about one axis results in offset of the second light plane and tilting about a second axis orthogonal to the first results in a shifting of the sector (112) within which the second light plane is projected, but tilting about either axis does not affect the orthogonality between the planes (108,110). Preferably the three or more reflective surfaces are defined by one or more prisms (104,106) formed of an optical material having an index of refraction which enlarges the sector angle encompassed by the second light plane when compared to mirrored surfaces supported within air. The performance of the diverter can be further enhanced by optical devices positioned at its input and/or output. The optical devices can be one or more conventional lenses or angled wedges of optical material.

Abstract: In a device for checking and sorting coins of different values by means of a coin tester connected to a control unit and with an outlet for admissible coins, the coin tester is followed by a sorting unit having three flaps. The sorting unit allocates the coins to different coin channels, leading to coin-stacking tubes, by means of electromagnets activated by the control unit according to the coins detected and coupled to the flaps. A first flap of the sorting unit can close two respective coin paths and is followed by a second and a third flap which can respectively be switched to and fro between two coin channels. The individual flaps of the sorting unit (13) are designed as narrow guide levers (21, 22, 23) which are mounted pivotably between a front wall (19) and a rear wall (20) of the sorting unit (13) in such a way that the coins roll over their periphery on the guide levers (21, 22, 23) in an upright manner. <IMAGE>
